make other people's lives happier

It’s always good to help people. Don’t let it get in front of your needs though. It’s too easy to hide in the problems of others to avoid your own. But the best thing to do is listen and let someone know you’re there for them if they need anything. Be open and understanding and be willing to put something about yourself on the table. That way others will be less scared to talk about themselves if you have opened up yourself. Just asking someone how they are at the beginning of most conversations can do a whole lot of good.
